The Record

STOCKTON - Two 18-year-old men were wounded in separate shootings in Stockton on Wednesday. Both were listed in stable condition with non-life-threatening injuries, authorities said.

The first shooting occurred about 11 a.m. in the 600 block of East Park Street. The victim told officers he was walking in the area when he heard gunfire, police said. The man ran away, noticed a burning sensation in his foot and realized he had been shot. The victim refused to cooperate with police and provided no description of the gunman, authorities said.

The second shooting occurred about 4:50 p.m. in the 800 block of Dallas Avenue, in the Conway Homes housing project. Residents said they heard about 10 gunshots. A short time later, police located a man with gunshot wounds to the arm and leg in the backyard of a nearby home on Elmira Avenue, authorities said. The shots might have been fired from a green Honda or Toyota that was occupied by three or four black men, police said.

TRACY - Tracy High School students and staff were evacuated shortly after 2 p.m. Wednesday when the school received a bomb threat, Tracy Unified School District officials said.

The evacuation was ordered after someone found graffiti in a boys' bathroom that contained a reference to a bomb on campus, district spokeswoman Jessica Cardoza said. School officials contacted police, who searched the campus with bomb-sniffing dogs and found nothing suspicious, Cardoza said.

Students and staff were evacuated to nearby Lincoln Park. They were allowed to leave when the school day ended at 3:02 p.m. Those who had vehicles in the school's parking lot were allowed to pick them up when police finished searching the parking lot about 7:30 p.m., Cardoza said.

She said Kimball High School received an unspecified threat last weekend that was also written in graffiti in a bathroom. School officials said they were trying to determine if Wednesday's bomb threat was a "copycat situation."

FRENCH CAMP - A stretch of southbound Highway 99 was closed for about three hours following a traffic collision shortly before 3:30 a.m. Wednesday, the California Highway Patrol said.

According to officers, the collision occurred just south of French Camp Road when a 24-year-old Stockton man in a 1999 Mitsubishi made an unsafe lane change and struck a dump truck. The Mitsubishi veered off the highway and overturned. The truck lost control, rolled onto its left side and dumped sand on the highway. There were no injuries, but the highway was closed for cleanup until about 6:30 a.m., officers said.
